To all whom t may concer Be it 1:rnown that I, ARTHUR I. ajcitizen of the United States, residingy at Elkridgge, in the county of Howard and State 5 of Maryland, have invented certain new and useful Improvements in Locomotive Driving' Boxes, oi which the following is 'a specilication. e e

This invention relates to an improved l0 driving box for locomotives Vand has as one of its principal objects to provide a construction wherein the box may, without 'removing' the locomotive drive wheels, be readily displaced.

The invention has :is a urth'erobject to provide a box employing a detachable face plate, where-iii the face plate may be readily released to be lifted out vertically and where in the box body inay then be shifted i1iwardly and removed.

A further object ol the invention is toV providev a construction wherein the Jrace plate will be connected at its upper end to the upper end ofthe box body4 by fastening" devices while at its lower end the box bodyl will itself be provided with ineans `for locking the lower end of the face plate thereto to thus eliminate the use oficastening devices at the lower end of the box body. j

And the invention has as a still :further object to provide a construction wherein the i 'face plate fastening' devices einployed will be retractible upon theboxbody jfor releasing the tace plate but wherein said fastening y devices wi ll, nevertheless, be held against accidental displacement troni the box body.

Other and incidental objects will appear hereinafter.

In the drawings: y u Figure 1 is an elevation looking at lthe inner vside of my improved driving box, the box being. shown in connect-ion with a locomotive drive axle and framel of conventional type.

rIn orderto `facilitate an accurateunderstandii'igrof the construction, operation and inouiiti'ng-ofiny vii-nproved ldriving box I have, inthe drawings, shown the invention in 'connection with a locoinotive traine l0 of conventional type. The binder Vbarot'the Vframe is indicated'at 11 and coacting with A`the legs respectivelyfof the frame isthe usual shoe 12 and wedge 13. A conventional Adrive axle Ais 'indicatedat 14, vthis laxle carrying 'at its adjacent end a drive wheel 1,5.

, In carrying the invention into effect I ein journal receiving recess opening vthrough the lower end thereof. Projecting' laterallylroin the outer side of the box body at the upper end portion of said'rec'ess lis a flange 'oi-projection 17`cionfor1nin'gto the outline ot the recess andhaving straight sides -j oined by an This aren ate a beveled facey 418,y sloping downwardly and outwardly toward the 'outer edge of.y the.. flange.' Seated vwithin the uppereiid portion 'of the journal receiving recess of 'the ybox body is a crown brass 19 supported at its `end'sby transverse ribs 20. n The crown brass bears over the adjacent journal ofthe axle- 14 inthe usual nia-nner and, ask will be observed, the flange 17 provides an extended bearing `for the crown brass at the outer' side of thebody, the flange being cut away to receiVe the brass and the ribs 2O extending across the end portions ot the flange at their lower terminalsi kAt 'its inner side the Lbox bodyvis formed with lateral flanges 21 coacting one with the shoe 12 and the other with vthe wedge at vthe inner vside ofthe freine.

Dependiiip; yfroin these V[langesrat t'heirlo-wer 'ends 'are lugs Q2 and projecting froinwthe lower ends of the side portions of 'the box [body at ytheir vouter edges` are loutwardly directed lugs or flanges 23 which depend below said side portions and 'substantially conforin in thickness thereto. At their 'upper ends` the lugs are provided with inwardly and downwardlyjsloping concave' shoulders 24 tilted in' the direction of the journal receiving recess of the body.

i'os

said flange.

Removably fitted over the drive axle 12 at the outer side of the trame is a tace plate 25. rhe side portions of this tace plate are, at their inner edges, provided throughout the major portion of their length with ilat vertical faces 26 adapted to snugly lit the straight end portions of the flange 17 ot the box body, whiler between the upper ends of said iaces, the plate is provided with an arcuate outwardly beveled edge 27 to snugly tit the beveled face 18 of At the lower ends of the faces 26, the inner edges of the side portions of the plate Vare cut away to provide inwardly and downwardly sloping convex shoulders 28 tilted to coact with the shoulders 24. rllhus, as will be seen in view of the preceding description, the box body may be slid along the drive axle at the inner side of the frame and projected through the frame when the face plate may then be inserted between the outer sideot the trames and e the wheel hub to be forced downwardly over sov plate is, as particularly shown in Figure f1 ,wear thereof.

the ange 17 and accordingly moved into active positionV embracing said flange.

lWhen thus in place, the face plate will, of course, seat vflat against the outer tace of the box body, the side portions of the plate coacting at their rear faces with the side portions of the box body, it being observed in this connection that the end portions of the flange 17 are of less thickness than'y the side portions lof the box body. Downward movement of the face plate will, of course, be limited by the engagement of the beveled inner edge 27 of the face plate with the bevelededge 18 of the flange as well as by the engagement ol' the shoulders 28 ot said pla-te with the shoulders 24 of the lugs 23.,

Upstandingftrom the -upper end of the plate at its outer side is anarcuateflange 29 and ormedin the outer side face of said an arcuate channel extending` about tht; opening through the plate. This channel is substantially dovetailed in cross section and engaged in the channel is a hub bearing 30. As will be observed, this bearing overlies the major portion of the area o'l' i the outer side of the plate and is presented to the hub ot the drive wheel to receive the As will be appreciated, the bearing may be renewed from time to'ytime as may be found necessary. Formed through the flange 29 as well as through the upper side portion of the bearing is an opening 31.

Formed through thebox body adjacent its'upper corners are openings 32 which, at their outer ends, enter recesses 33 in the outer side of the box body.k through said openings are bolts 34 provided, sis-particularly shown in Figure 6, with flat heads 35 adapted to be freely received within the recesses lying Hush with tl outer Freely fittedl side oit' the box body and provided with convex inner end edges. Threaded upon the bolts are nuts 36 and it is now to he o`bserved that the inner ends olf these bolts provided with openings 37 therethrough at substantially right angles to the heads 35. These openings are designed to receive Cotter pins 38 for locking the nuts against displacement. Formed through the upperV end of the Ylace plate adjacent opposite ends of the flange 29 are slots 39 which enter cylindrical recesses Ll0 in the inner side ot the plate, these recesses openingthrough the bearing 30 and the bottom walls thereof being provided with concave seats at substantially right angles to the slots. .The slots are adapted to freely receive the heads 35 of the bolts therethrough while the rccesses 10 are such diameter that the bolt heads may loosely turn therein. is will thus be appreciated, the bolts may, without ,edges of the heads thereof in the concave seats of the bottom walls of said recesses for locking the bolts ,against rotation when the bolt heads will coact with the 'face plate so that ythe nuts 3G may be tightened for securely bindingthe plate against the outer side oit the box body.A Y y Attention is now directed to the tact that when the face plate is, as inst previously described, secured in place, the plate will be iirmly held against upward movement so that the should rs 28 of said plat-e will be maintained in binding engagement with the shoulders 211 ot the lugs 2S oli the box body. Consequently, these shoulders will lock the lower y end portions oit the plate tightly against the box body. The shoulders will. thus coact with the bolts 34 foryfirmly securing 'the faceplate flat against the outer side of the box body and will eliminate the necessity for the use of fastening devices similar to said bolts at the lower end ot the y face plate. Further, said shoulders will, as will be seen, coact to lock the end portions of the face plate against spreading. The tace plate is, as will be particularly observed upon re'lerence yto Figure 4, of a width to overhang the box body at its outer `side so that the face plate will thus provide Cil upwardly and removed. :body maybe readily shifted inwardly along vthe drive axle and also removed. I accordeliminate possible undue strain upon the outer end portions of the bolts 34;.

To remove the box, vthe nuts 36 of the bolts are first loosened and in this connection it is to be observed that since, as previously noted, the openings 39 through the inner end portions of the bolts lie at substantially right angles to the bolt heads 35, said'openings will provide a means whereby the Josition of the bolt heads with respect to t e. vertical Vmay be readily determined. Consequently, after the nuts 3G have been loosened, the bolts may be rotated to easily position the bolt heads in alinement with the slots 89 in the face plate, when the bolts 'may then be .retracted for drawing the bolt `heads through the face plate and into the recesses 33 in the box body. The face plate will then be freed so that a suitable tool may be engaged in the opening 31 through the .fiange 29 of said plate and the plate lifted This done, the box ingly provide a construction whereby the Lbox may, without removing the drive wheels, be readily displaced.

diiiiculty, access may be readily had to the.

Thus, with minimum shoe and Wedgeand, as will be noted, the shoe and wedge may, without removing the lframe jbrace, be also displaced. Accordinglower side ofthe adjacentjournal ofthe drive axle and, at rits upper end, abuts the lower edges of the ribs 20. Itemovably supporting the cellar in place is a plate 43 detachably securedL by bolts 44 engaged through the lugs 22 and 23 of the box body. As will be noted, the cellar is provided at its inner end with a sight window 45 in order that the level of the grease within the cellar may be readily ascertained. However, since this cellar is to be made the subject of a separate application it will not be further described herein. i
